Elements
The elements included in actinides are Actinium, Thorium, Protactinium, Uranium, Neptunium, Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, and Nobelium.
Group and Period
Actinides fall between groups two and three and are in period seven.
Solid, Liquid, or Gas?
In the Periodic Table of Elements, Actinium through Uranium are solids and the rest are unknown so they're not found in nature.
Physical Properties
Actinides have many physical properties including that they are very dense and heavy metals. They are also silver, silvery-white, or grey. Actinides have conductivity which is the ability of metals to transfer heat or electricity to any other object.
Chemical Properties
Actinides also have plenty of chemical properties. All Actinides are radioactive and they tarnish readily in air. Actinides also combine directly with most nonmetals. Common Uses
The explosive power of Uranium and Plutonium are used in the making of atomic bombs. Curium and Plutonium are used as power sources on the Moon to provide electrical energy for transmitting messages to Earth. Plutonium is also used in implants in the human body to power the heart pacemaker.
Interesting Facts
The Uranium atom bomb that exploded over Japan was the first Uranium bomb released. Actinides get their name from the first element in the period, actinium, and from the greek word “atkis” which means ray, showing that all of the Actinide Elements are radioactive. The Actinides have less similarity in their chemical properties than the lanthanoid series.
